Batt Insulation Dunluce Edmonton

Mineral wool and fibreglass batts in Dunluce walls and ceilings

A batt only performs if it fills the cavity completely and is not squashed. In Dunluce the two things that ruin it are compression — jamming a wider batt into a narrow bay — and gaps around wiring and boxes, where the insulation is stuffed behind rather than split around.

• Rim joists insulated and air-sealed
• Vapour control detailed before the board goes on
• Mineral wool where fire or sound performance matters
• Split and fitted around wiring and electrical boxes
• Batts friction-fit to full cavity width, not compressed
• Odd bays cut to fit rather than packed

Batt Insulation Dunluce Edmonton: your questions answered

What about the wiring in the wall?

The batt gets split so part sits behind the cable and part in front, and it is cut around boxes. Stuffing it behind the wiring leaves an uninsulated void right where there is already a hole in the vapour barrier.

Why is my Dunluce basement cold along the floor edge?

Usually the rim joist. It is thin, directly exposed to outside, and in most basements it is bare or has a batt tucked loosely against it. It needs air sealing first, then insulating.

There is a water pipe in my exterior wall. What happens to it?

Wherever the plumbing allows, the insulation goes behind the pipe so the pipe stays on the heated side. If it cannot, we flag it rather than boarding over a line we know is exposed to freezing.

Do you install the vapour barrier as well?

Yes, and the order matters. Insulation is completed first, the barrier goes on the warm side and is sealed at penetrations before boarding. None of it can be corrected once the drywall is up.

Can you insulate my finished walls without removing the drywall?

Not with batts — they need an open cavity. That is a job for a blown-in or injected product, or for adding insulation on the room side. We will tell you that rather than sell you a partial job.

What about the pipes in my exterior wall?

Insulation goes behind them, between the pipe and the outside, not stuffed in around them. A water line on the cold side of the batt is a freeze risk in an Alberta winter, not just an efficiency question.
